The following statements are equivalent: T is one-to-one. For every b in R m , the equation T ( x )= b has at most one solution. For every b in R m , the equation Ax = b has a unique solution or is inconsistent. Ax = 0 has only the trivial solution.

Web31 okt. 2012 · After all, if det (magic (4)) gives us 1e-12, then 1e-100 must correspond to a singular matrix! But it does not. Even worse, det (.0001*eye (100)) ans = 0 In fact, the determinant is scaled by 0.0001^100, which in matlab will be 1e-400. At least that would be true if matlab could represent a number that small using a double. It cannot do so.
